I'm really intrigued by the Kythera and all the potential build options and tinkering possibilities. Is it any good, or would I just be shooting myself in the foot? Disclaimer, yes I know it's semi only and all that jazz, that doesn't really bother me. Couple of main questions: - Is it efficient? (all day air is 12 DOLLARS at my home field. I hope the air is like magical or something) - Picky with buckings/hopups like the jack can be? - Is it prone to problems? I've had too many unreliable guns to deal with another one. - Overall is it any good? Maybe for easy reference, do a scale of 1-10. Thanks in advance!
